📄️ Arrays
Discover how to use TypeScript arrays to create typed collections, add and filter elements, efficiently iterate, sort objects, merge arrays, and identify duplicates.
📄️ Lists
Implement list data structures in TypeScript using arrays and custom classes with proper generic type parameters.
📄️ Append to Arrays
Add elements to TypeScript arrays using type-safe methods that preserve array typing and handle immutability correctly.
📄️ Remove Item from Array
Remove elements from TypeScript arrays using type-safe methods that maintain proper array typing and immutability patterns.
📄️ Array Map
Transform arrays in TypeScript using map while preserving type safety and creating new typed collections efficiently.
📄️ Reduce
Explore TypeScript's reduce method to transform arrays into any data structure you need while maintaining full type safety.
📄️ Filtering
Implement type-safe array filtering in TypeScript that preserves the correct return types using built-in methods and custom type guards.
📄️ Array Filter
Filter TypeScript arrays with type guards that narrow element types and preserve type safety in the resulting collection.
📄️ Tuples
Create fixed-length, ordered collections in TypeScript using tuples to model structured data with precise type definitions.
📄️ Map
Learn how to use the Map object in TypeScript with proper type annotations to create, manipulate, and iterate over key-value pairs.
📄️ Record
Learn how to use `Record<K, V>` in TypeScript to create strongly-typed object maps, and when it's better than regular objects.
📄️ TS Dictionary
Learn how to use a TypeScript dictionary to create and define key-value pairs, iterate efficiently, handle optional keys, ensure type safety, merge dictionaries, and update values.
📄️ Set
Discover how to utilize TypeScript Set for adding, removing, and checking elements, iterating, converting to arrays, and comparing Sets for equality.
📄️ Hashmaps
Create efficient, type-safe hashmaps in TypeScript using Map objects and interfaces to ensure predictable key-value access patterns.
📄️ Map Type
Build flexible generic map types in TypeScript that transform object properties while preserving type safety.
